I use the open source equivalent classicshell on my windows 8 install on my EEE netbook.
The new start screen and UI are nice, but do not function well on a 7-inch screen. In fact most of the apps won't even open, they just give me an error message that the screen size is not support. Surprisingly the IE app won't open for this reason.
I would have thought the new ui to be perfect for my 7inch screen but it is worthless on small screens because there are very few apps that will work on it.
Its worthless on large screens because I like the ability to see multiple windows open on my 25 inch monitor.
